View System Information Menu
The View System Information Menu consists of only one display screen
which indicates the version number of the firmware that is running the
instrument and the system voltage. The system voltage is the voltage that
is directly running the instrument’s circuitry.
NOTE: The Information Screen is not a good indicator of battery life
because the power converter will operate as normal and have an
output of 24 volts until the 12 VDC battery dies.
ALARM-2 OFF DELAY
(0 sec) The amount of time the Rig Monitor delays turning off the alarm 2 circuit
once an alarm 2 condition passes.
ALARM-2 (activation)
(INCREASING) Indicates if the alarm 2 circuit is activated by gas readings INCREASING
or DECREASING to the ALARM-2 Level.
ALARM-2 Relay (action)
(NORMALLY DE-ENERGIZED) If set as NORMALLY DE-ENERGIZED, the channel’s alarm 2 relay is de-
energized in normal operation and energizes when an alarm 2 condition
is initiated.
If set as NORMALLY ENERGIZED, the channel’s alarm 2 relay is
energized in normal operation and de-energizes when an alarm 2
condition is initiated.
ALARM-2 Relay (reset)
(LATCHING) If set as LATCHING, you must press the RESET button to reset the
alarm 2 circuit after the alarm 2 condition passes.
If set as SELF RESETTING, the Rig Monitor automatically resets the
alarm 2 circuit after the alarm 2 condition passes.
NOISE FILTER
(3) The noise filter feature helps “smooth out” jumpy or noisy signals from
the detector head. You can set the noise filter from 1 to 8.
A setting of 8 produces the greatest amount of smoothing but also
responds slowest to changes in the response reading.
A setting of 1 responds fastest to changes in the response reading but
produces the least amount of smoothing.
ZERO SUPPRESSION
(2% of the detection range in terms of
the detection units) The zero suppression feature helps prevent “jumpy” readings near the
fresh air reading.
For example, if the zero suppression setting is 2.0% and the full scale is
100% LEL, the Rig Monitor will display a reading of 0% LEL for gas
readings from -2% LEL to 2% LEL.
